In a method and system for corrective bunionectomy surgery of a bone, a saw template is positioned at a proximal portion of the bone. The saw template has a plurality of pin holes, for the insertion of pins. The saw template is replaced with a saw block placed over a portion of the plurality of pins. The bone is cut into first and second bone segments based on a position of the saw block. The saw block is removed. A corrective angle is applied to the second bone segment relative to the first bone segment. A mating plate compatible with the corrective angle is positioned over the plurality of pins to join the first bone segment and the second bone segment. A plurality of bone screws is screwed into the mating plate to secure the first bone segment and the second bone segment to form a corrective construct.
